Have we ever got mileage claimed by an OEM from your vehicle? Why don’t we get this declared mileage?

And the obvious answer is that the vehicles are tested under standard conditions and the actual driving conditions in India differ a lot from these standard conditions. So the question is how I can get the maximum mileage from my vehicle?

One way is giving our vehicle the best maintenance – which we are sure that most of the people in this community do and secondly, the most important and toughest part is to always run the vehicle in the best economy zone of the engine.

If we are able to achieve these necessary skills to control the clutch and the gear lever, we will be able to achieve the magic number like 46 Kmpl from Tata Indigo Manza what Mr. Narayanan Menon (Limca book of world record) has achieved in past.

Considering the road conditions, traffic conditions and driving skills of an individual it is very difficult to maintain your engine in that narrow economy zone. Generally speaking, it is very difficult to master such skills for most of the day to day drivers.

Other way round to this problem is why not to make ‘smart cars’ like smart phones. Instead of trying to train everyone to be an intelligent driver, what if we incorporate intelligent driving skills into our cars? With this as the guiding motto, we have come up with a technology which implements ‘Intelligent driver logic’ into our vehicles through a Motomatic Hybrid transmission.

Motomatic hybrid transmission is an indigenously developed hybrid drive solution for Indian scenario. The concept is based on Motomatic hybrid transmission (patent pending), an electric CVT which is all geared transmission and hence is very efficient. This transmission concept elegantly integrates electric CVT with different hybrid modes like Series mode, Power-split mode, Parallel mode, Mechanical drive and Electric drive mode (more information at http://en.wikipedia.org/wiki/Hybrid_vehicle_drivetrains). The Motomatic hybrid Transmission ensures that the engine runs under most efficient operating conditions in all circumstances, hence disconnecting the impact of driver skill and road conditions on vehicle mileage to large extent.

The major features of this technology are:
1. The Motomatic transmission comprises of only positively meshed gears.
2. No friction members like clutches, brakes or belts - this makes it a highly efficient transmission.
3. With this CVT we can achieve infinite speed ratio range; hence the engine can always operate in most optimum speeds to produce demanded power. This de-couples effect of driver skill on vehicle mileage to larger extent.
4. The speed ratio change is self-actuated, thus no need of electronic control for CVT action.
5. Electronic brake and clutch present in the system are only actuated to shift between modes of hybrid functions and hence very less power losses incurred due to engagement and dis-engagement.
6. With the use of ‘Artificial Intelligence’ related to optimum Engine operating conditions and driving skills, this technology has potential to improve vehicle mileage by 65-75 %.
7. Speed ratio zero is possible, so no clutch is required on engine side to disengage engine while braking and idling.
8. The technology is related to a transmission / gearbox, and hence can also be applied as retrofit to present on-road vehicles.

The Hybrid concept belongs to combination of series-parallel hybrid category. This makes it suitable transmission for following vehicles driven in mixed city-highway drive cycles like:
1. Personal car, City taxi, Intercity taxi
2. LCV like Tata Ace
3. 2-wheelers
4. 3-wheelers

Present scenario in India
Most of the automobile majors are striving to acquire or develop their own Hybrid technologies to comply with governmental emission norms and offer end customers products with higher performance at lower operating costs. They have invested heavily in acquiring and developing technologies related to electric and hybrid vehicles. Local automobile market segments like two-wheelers, passenger cars, LCVs and buses are witnessing the introduction of alternate fuel vehicles and hybrid electric vehicles. In last couple of years, two wheeler EV market has received considerable attention from customers. This indicates the paradigm shift in the mind set of customers and the acceptance to the newer electric mobility technologies.

Status of MHT Technology and strategy:
• Recently we have demonstrated first working prototype (Proof of Concept) at IIT Bombay TechFest 2014 in 3-5th January 2014. We got an overwhelming response from OEMs and Government agencies.
• Our present objective is to build a concept hybrid car based on Motomatic Hybrid Transmission technology and showcase the concept at International Auto-show platforms like Frankfurt Auto-show, Detroit Auto-show.

We are demonstrating this technology again at Technology Festival of IISc, Bangalore "Pravega" on 31 Jan 2014 to 2 Feb 2014 http://pravega.org/exhibitions#exhibitions. To have a live experience of the technology please visit the event.

Would love to know more. I mean technical information, rather than ad copy!

What are you doing about international patents?

Hi Sutripta,

Thanks for the interest shown. The above post describes a technology related to a highly technical field of hybrid vehicles. Hence keeping in mind the interest of all team-bhp members, we have given a brief technology information. I feel that if you can give fair time to go through this article, you will find all technical details in it. I will be glad to answer your technical queries, if you ask for specific details, rather than asking in general manner.

Regarding patent application, we have secured our technology with patents, however any discussion on this aspect is not relevant to this forum.

^^^
From the 'geared neutral, I take it that it is a epicyclic with two inputs (which can be algebraically added) to the one output. Am I correct? In which case, would like to know what is different in this.

Could find no technical details in this thread. Could you point out which sections exactly.
